CDKN2C and type 2 diabetes mellitus: As one more example, we highlight the gene CDKN2C, which colocalizes in the muscle with T2D, WHR, and TG despite that the GWAS variant lies directly within an intron of another gene, FAF1. CDKN2C has seven PPI interactions with known IR/T2D genes and is differentially expressed under glucose stimulation.
